Top U.S. and NATO officials reiterated on Wednesday that they would not impose a "no-fly" zone over Ukraine, after Ukrainian President Volodymyr Zelensky called the West "an accomplice ignoring terror."
Why it matters: Enforcing a no-fly zone would require US. or NATO forces to destroy Russian air defenses and shoot down Russian aircraft, dramatically raising the risk of a broader war between nuclear powers. NATO countries are considering alternative steps, like providing anti-aircraft missile systems or potentially fighter jets.
